Been Around the Block
OK, I checked compression and I saw 140psi on the left cylinder and 90psi on the right. That seems like it could be a real problem. The left side is the one that has been running rich. I put a #30 pilot in and changed the main jets to 165. I started it and took it for a spin and there is still very little power when I twist the throttle. I could barely make it up a slight hill from standstill as it wanted to stall. I haven't checked the timing yet, I don't have a light and haven't used one before. When I set this up I used a test light and made the adjustment from that.
